Explosion Experiment

About This Video

1st and 2nd grade AIM students helped me perform this "Explosion Experiment" while studying ancient Chinese contributions and inventions. One of today's topics was gunpowder, so we made our own explosion with Mentos and Diet Coke. We learned that each Mentos is covered with thousands of microscopic pits where the cola bubbles get trapped. The Mentos sink while the bubbles rise. With that many bubbles rising to the top simultaneously, the cola is pushed out in a geyser like explosion.
